I wanted to know how to access a certain element of a struct in the way I'm defining it. Here is my struct:
typedef struct {
char *produtos[200000];
int contador;
} Produtos,*ProdutosP;
I set ProdutosP p as a pointer to the struct. I added the first string of char *produtos[200000] using p->produtos[0] but I wanted to access the first string of the first string.
How do I get it?
I used the first string of
char *produtos[200000]usingp->produtos[0]but I wanted to access the first string of the first string.
p->produtos[0][0]
or
*(p->produtos[0])
You have defined products as an array of string pointers.
To access the first character you only have to use one more []
In this case p->produtos[0][0] . The first number between parentheses is the string and the second character.
That is, the number in brackets dereferencing the string at position n and the second character in the chosen position.
The link I added is in English if you prefer to have one in Spanish at wikipedia.
